摘要
城市地下管线系统是城市的“生命线”。以城市供水管网信息系统为例,对面向网络的管网信息系统的总体功能进行了详细的设计,提出了基于混合模式的系统实现技术,并对管线数据编码和数据库设计、受影响区域搜索以及数据库驱动的Web3D建模等关键技术进行了分析与探讨,为此类应用系统的建立提出了一种实用的可行方案。
Urban underground pipeline is the lifeline in a city. Taking the water supply pipeline as an example, an overall function for the internet-oriented pipeline information system was designed in detail. At the same time, a sort of mixed pattern realization technology was put forward. Secondly, the key techniques-the pipeline data encoding & database designment, influenced areas search and the data- base-driven pipeline dynamic three-dimension modeling were discussed. Itprovided afeasible solution to such kind ofapplication system.
